I want to create skills/powers specific trees and the simplest way to do it, is i think through engrams.
But after some tests and researches, I find it’s impossible to disable an engram if an other had been chosen.
I think about others solutions but i don’t know which one are possible :
Make the admin able to spawn a one-use blueprint to learn the tree’s base engram
Editing the character creation menu in wich you can chose a tree and having a different set of engrams
If editing the character creation menu can be an issue, create an UI that spawn at a certain level to make the choice that enable the base engram
making an unthrowable and unstolenable object in the inventory (as the implant, create through character creation menu or other way) a pre-requisit to learn an engram
Do you know if at least one of those is feasible or do you have others solutions that can do the thing?
